    I think my diff has been changed. When doing the rotation count trick does the entire rear need to be lifted because of the limited slip. I raised the passenger side only and and got 2 1/4 drive shaft turns per wheel rotation. Can't be right. Also when I purchased the car it had an EPC P7 power plug installed. I've never heard of this and can't find any info has any one heard of this.

    Power plug? Like in the OBD port or on the ECU? And yes both wheels off the ground.
